I’m not quite sure why, but Blue Grenadier is a little overlooked in Australia. At almost half the price of many other fish varieties, it’s a hidden gem. At first, I assumed it was imported from Asia, which explained the affordable price—but I was wrong. Blue Grenadier is wild-caught in the pristine waters of Australia and New Zealand. It’s also known as hoki and is sometimes sold as blue hake in other parts of the world.
What Does Blue Grenadier Taste Like?
Once I discovered that Blue Grenadier is wild-caught in Australia and New Zealand, it quickly became my go-to fish. It has a delicate, slightly sweet flavour with moist, flaky flesh that cooks beautifully in the oven. Best of all, it cooks in under 20 minutes, making it perfect for busy weeknights. My family absolutely loves it, and in my opinion, baking is by far the easiest and most delicious way to prepare it.
Ingredients
You’ll only need five simple ingredients:
- Blue grenadier fillets – or substitute another mild white fish like snapper, halibut, flounder or tilapia.
- Lemon – you’ll need both the zest and juice.
- Butter
- Garlic
- Sea salt and black pepper
How to make it
This is an easy recipe that’s perfect for a quick weeknight dinner. Even beginner cooks can make it with confidence.
- Preheat your oven to 200°C (400°F).
- Peel and mince the garlic. Zest and juice the lemon.
- Line a baking dish or oven tray with baking paper.
- Melt the butter in a small saucepan over low heat. Remove from the heat, then stir in the garlic, lemon zest and lemon juice.
- Add lemon zest, juice and minced garlic into the pan with melted butter.
- Place the fish fillets on the prepared tray and season with salt and pepper.
- Spoon or brush the lemon butter mixture evenly over the fish.

Recipe FAQs
Raw blue grenadier should be cooked within 1–2 days of purchasing. If you don’t plan to cook it within that time, freeze it for later.
The fish is cooked when it flakes easily with a fork at the thickest part of the fillet. If you’re using an instant-read thermometer, the internal temperature should reach 145°F (63°C).
I don’t recommend freezing this recipe. The fish tends to become watery and lose its delicate texture once thawed.
